Olivia Wilde wears Gucci on the red carpet

Olivia Wilde makes tuxedos look sexy. Like really, really sexy.

Jason Sudeikis is one lucky guy.

That's basically all we can think after spotting his fiancée, Olivia Wilde, at the London premiere of her new film, Rush. The actress walked the red carpet in a tuxedo... without a shirt or bra underneath.

We're hoping she added quite a bit of double-sided tape, because the black Gucci creation with satin lapels only boasted one button. Daring, yet not too in-your-face.

Her confidence — which we think has something to do with turning 30 — helps her pull it off. The actress recently penned a piece for Glamour in which she advises all of her fellow 30-year-olds to forget the past and embrace their flaws.

"Take care of yourself now that you're old enough to know how," she advises. "Drink water, sleep eight hours (I wish), and don't go within 400 feet of a tanning booth or I'll slap you. Hard."

Oh, and stop dressing "like a hobo."

The actress is taking that approach to her wedding-day fashion.

The actress will wear a Monique Lhuillier dress when she walks down the aisle, but her bridesmaids won't be forced to adhere to "that tortured tradition of forcing them to wear a ridiculous dress they'll never wear again. They'll have a real creation tailored for each of them," she told InStyle in July. "They can dye it black or purple and wear it forever."

We have to wonder: Will the groom — and the groomsmen — take a play from Wilde's book and shy away from shirts under their tuxedos on the wedding day? Somehow, we don't think it would look as sexy as her interpretation of the look.
